Fast does not imply flawed: Analyzing emergency physician productivity and medical errors.

Area of Science:

• Emergency Medicine
• Healthcare Quality Improvement
• Patient Safety

Background:

• Medical errors pose a significant risk in emergency departments.
• Understanding factors influencing medical error rates is crucial for improving patient safety.
• Physician productivity is a key operational metric in emergency medicine.

Purpose of the Study:

• To investigate the association between emergency physician productivity and the incidence of medical errors.
• To identify specific productivity metrics that correlate with medical error risk.
• To inform strategies for optimizing emergency department workflow and patient safety.

Main Methods:

• Retrospective analysis of quality assurance and billing data from two urban emergency departments over three years.
• Inclusion of faculty physicians with a minimum of 400 hours worked.
• Measurement of physician productivity using patients seen per hour (PPH) and relative value units billed per hour (RVU/h).
• Calculation of medical error rates per 1000 patients based on adjudicated quality assurance data.
• Statistical analysis using Kruskal-Wallis testing to examine relationships between productivity metrics and error rates.

Main Results:

• Data from 81 physicians across two sites were analyzed.
• Site A showed an association between RVU/h and error rates (P=0.03), with slower RVU/h quartiles having higher error rates.
• Site B demonstrated a link between PPH and error rates (P<0.01), where slower PPH quartiles were associated with increased errors.
• No significant association was found between PPH and error rates at Site A, or RVU/h and error rates at Site B.

Conclusions:

• Medical error rates are associated with physician productivity metrics in emergency departments.
• Higher rates of medical errors were observed among physicians with slower productivity at both sites, though the specific metric varied.
• Findings suggest that physician productivity, when measured by PPH or RVU/h, may serve as an indicator for potential patient safety risks.
